This morning when I woke up I found my Antminer L3+ running at idle. When I rebooted the machine via the GUI, it started mining and everything appeared to look good. I changed the mining pool and the miner restarted, and then started rebooting on it's own. When I logged into the GUI I saw this error: "Socket connect failed: Connection refused" I tried resetting the unit, re-flashing the firmware via the instructions provided on Bitmains' support page. Nothing worked. It's been rebooting for hours with the same error. I've contacted Bitmain, but who knows when they will respond. The miner is only a week old. Any help is greatly appreciated.
